Docker run command, expose port private only

  • 772
docker run -it -p 8080 myimage /bin/bash

I would expect the code above to expose port 8080 private. However when I run:

docker ps -a

It shows:

0.0.0.0:32770->8080/tcp

How does one set port 8080 to expose only private?

port

    Just realized that it is by default open within the host, so just removing the port flag from run was enough.

    Bonus: You may map a port to the host directly via the flag -p 127.0.0.1:8080:8080
